high frequency steel pipes automatic mill

The high frequency steel pipes automatic mill is specially used for producingΦ19-Φ63.5mm, δ0.8-2.5mm high-frequency straight seam welded pipe and corresponding square pipe and special-shaped pipe(δ≤2.0mm).

high frequency steel pipes automatic mill

The composition of equipment is from uncoiler to fixed length cutting saw. Rolling
speed can be adjusted correspondingly within suitable range of pipe diameter and
wall thickness.

Material:Hot rolled or cold rolled low carbon steel
Dimension range of processing steel pipe:
(1) O.D.: Φ19-Φ63.5mm
(2) Wall thickness: 0.8-2.5mm(square pipe and special-shaped pipeδ≤2.0mm)
(3) Length: 4-8m

Equipment Make-up
1. Un-coiler
2. Vertical Loop
3. Molding Set
4. Flying Saw
5. Output Rollway
6. Solid High-frequency 60 kW+ DC Drive

Product (steel pipe) process flow:
Raw material (steel coil) → uncoiling → shearing and butt-welding → material accumulating → non-power leveling →mill-forming → high-frequency welding → removing burrs outside of weld seam → cooling → sizing →
roughly straightening → fixed length cutting → run-out table
